Problems With the First Recommendation in Level C: “Because uterine rupture may be catastrophic, VBAC [vaginal birth after cesarean] should be attempted in institutions equipped to respond to emergencies with physicians immediately available to provide emergency care.”

The first problem with this recommendation is that of the eight final recommendations, it is this one which has the largest impact on maternity care in the United States. Yet by the American College of Obstetricians and Gynecologists’ (ACOG) own admission, there is no evidence to back up this recommendation. This is of course the reason this recommendation has been placed in Level C, thus making it ACOG’s confession that since there are no data, ACOG will simply have to go on the basis of “expert opinion.” This is a sad regression to the days of “Trust me, I’m a doctor”—in spite of the new direction of medical care to evidence-based practice.
